Specification of Letters Patent.

'Patented Oct. 1, 1918.

f Application filed February 15. 1917. Serial No. 148,746.

To all whom t may concern.'

Be it known that I, ALONZO EDWARD i RHODES, a citizen of the United States, and

`sus

a resident of Hillcrest, Delaware, have invented certain Improvements in Turnstiles,

of which the following is a specification.

The object of kmy invention'is to provide a simple form of turnstile, arranged for movement in one direction only; being normally locked against movement 'in either direction, and provided with 'suitable releasing means whereby it may be readily placed in condition to'move in one direction i as desired. `A further object of myinvention is to construct a turnstile designed to move 1n one dlrection only 1n such manner that reversal of a part of the structure permits a change lin the direction of its movement; in one position being a right hand turnstile and in another position a left Ihand turnstile. If desired, I may combine ing a modified construction within the scope.

ofl my invention.

In the drawings, a pedestal mount for the turnstile structure is shown at 1, which may comprise a hollow base 2, secured in position by any suitable means, and a head 3 which may be integral therewith. The lower part of the head'is providedwith a shoulder 4,

and its upper end has a bearing flange 5.

Mounted upon the head of the pedestal is a tubular shell or casing 10, carrying a plurality of arms 11; such shell or casing having a flange 12 adaptedto the shoulder 4: of the base, and an internal Yflange or shoulder 18 adapted to engage the be ring flange 5 at the upper end of the pedestal head 3.

Pivotally mounted Iin a slot 3 in the head 3 is a gravity pawl l5 adapted to engage ratchet teeth 16 formed in a liange or shoulder 17 carried by the shell 10 to prevent backward movement of said shell with respect to the head. Below the flange or shoulder 17, a third flange or shoulder 18 is disposed on the inner wall of the casing l0, having four teeth 19 for engagement with the end of a catch-bar or locking member 20 vertically mounted and movable within the base of the pedestal, with its upper end disposed in a slot 3b in the head 3. This catch-bar is preferably a gravity-operated structure, and may be connected at its lower end 21 to a foot lever 22 pivoted at 23 to the pedestal base. In its normal, lowered, position, this catch-bar lies with its upper end in engagement with one of the teeth 1'9 to prevent movement of the shell 10 journaled on the head 3 at the upper end of the v edestal by engagement with its arms 11.

eans are preferably provided for guiding the upper end of the catch-barl or locking member 2 0, and such means, in addition to the slot 3a in the head 3, may comprise posivtioning screws 24 and 2.5, carried by the pedestal 1 and disposed in engagement with the catch-bar at front and back of the same.

When it is desired to permit o eration of the turnstile to admit a person, t e operator presses down upon the foot lever .22, therebyraising the upper end of the catch.- bar from engagement with one of the teeth 19 and the turnstile is free to move in one direction, depending upon the position of the teeth engaged by the pawl 15. Should it be desired to lock the catch-bar out of action so that the turnstile can be moved continuously, in onedirection of course, I provide a pin 26 adapted to hold the foot lever when lowered to the housing 27 of the base Vin which it is journaled and thereby maintain the catch-bar in the raised, inactive position.

It will be understood, of course, that the position of the ratchet teeth 16 and 19 within the shell 10 determines the direction of movement of the casing 10 and the arms 11, and that in order to provide right-hand and left-hand turnstiles', it is necessary to provide the 'respective -casings with ratchet teeth 16 and 19 facing in opposite directions, respectively. For this purpose, the said ratchet teeth 16 and 19, or their equivalent, faced in the desired direction, may be carried by removable members which may vals be set as desired in the casing; depending entirely upon the direction the arms of the turnstile are to move, and fixed in such position to the flanges 17 and 18 for proper coact-ion with theA pawl 15, and lockmg member 20.

In some instances, it may be desirable to provide a complete rotatable structure avaiI- able for use in turnstiles to be moved to the right or left, as the circumstances ofplacing such structures may,require. To this end, I may provide acasing such as shown at 10l in Fig. 5, having sets of ratchet teeth at top and bottom of the same; in one of which sets the respective teeth'lie in one position, and in the other of which the teeth lie in the opposite position, respectively.

In this arrangement, the flanges 17 and 18 at the bottom of the casing carry teeth 16 and 19, while the flanges 17 and 18, shown as disposed at the top of the casing, carry teeth 16*1 and 19", respectively. The mechanism of the turnstiles shown in Figs. 1 and 5, is so arranged that the arms 11 must be -moved to the left,or clock-wise. By reversing the casing shown in Fig. 5, with respect tothe head 3, the ratchet teeth 16a and 19il will 'be in position to permit the arms of the turnstile to move to the right, or counter clock-wise when the locking member 20 is lifted or released from its engagement with one of the teeth 19. In the structure shown in Fig. 1, a special flange 13 is provided for .engagement with the bearing flange 5 of the head. In the arrangement illustrated in Fig. 5,. the flange17 engages said bearing flange.

Should it be necessary or desirable to as' certain the number of persons assing through the turnstile, the head 3 of t e pedestal may be providedv with a suitable registering device, the casing. of which is indicated at 28 and as secured'to the bearing flange 5, 'and having an operating arm 29 extending outside said casing and adapted to be acted upon by lugs -30 preferably arran ed in line with the external arms 11 oarrie by the shell 10 and disposed on the inner wall of the same. The top of the shell or casing l0 may have a glass plate'31 so f that the numbers of the 'registering device ,may be readily viewed.

' disposed with its ratchet teeth, 19 or 19,

inverted with respect to said counting device. These teeth may be employed as the means for actuating the counter; the latter being provided with an operating arm 29a extending upwardly for contact therewith and engaged successively by the four teeth. The flange which receives the glass plate 31 in the construction shown in Fig. 5, will rest on the shoulder 4, when the casing 10 is reversed.
